Wood had recovered the famous Iwo Jima flag from a salvage depot at Pearl Harbor, and brought it aboard the Navy vessel LST-779, where he was a communications officer, according to the Pasadena Star News. His ship was among some 450 that had amassed for the 1945 US assault on the key Pacific island.

"I was on the ship when a young Marine came along," he explained in the newsletter. "He was dusty, dirty and battle-worn, and even though he couldn't have been more than 18 or 19, he looked like an old man.

" 'Do you have a flag?' he asked me. 'Yes,' I said, 'What for?' He said something like, 'Don't worry, you won't regret it.' "

The US military decided they need to take the Pacific island of Iwo Jima. It was to be a critical refueling stop for US aircraft in the assault on Okinawa, Japan. But the Japanese had some 20,000 soldiers dug in – literally in tunnels crisscrossing the island.

While the battle for Iwo Jima took 36 days to complete, after just four days, a group of US Marines was sent to the 556-foot summit to plant a US flag. According to the US Navy Department Library, some 40 men from 3rd Platoon, E Company, 2nd Battalion, 28th Marines, led by 1st Lieutenant Harold G. Schrier, raised the flag on Feb. 23, 1945.

"At 10:20 a.m., the flag was hoisted on a steel pipe above the island. This symbol of victory sent a wave of strength to the battle-weary fighting men below, and struck a further mental blow against the island's defenders," according to the official Navy history.

Three hours later, a second patrol was ordered to replace the flag with a bigger one. Some reports say it was to make the flag more visible, others say that an officer wanted the first flag as a souvenir.
